AFX Bridge: $24.15M USDC Exploit on Arbitrum

AFX bridge suffered a $24.15M USDC crypto bridge exploit on Arbitrum when an attacker withdrew the funds to Ethereum using five signatures from a seven-validator set. The move signals a likely validator key or backend compromise. Validator addresses tied to the transaction include 0x00BB84aF06daC03BFe744Da13dF9D2D6fd8e77E5 and 0x0C95AB7e26Df9F63cc6E06DF8ee897B822d8C77c among others listed in the on-chain report. This USDC withdrawal attack highlights persistent risks in multi-sig bridge designs even as total value locked in cross-chain protocols remains elevated.
